2.5" 4-Layer Black Aluminum Voice Coils Wound with OFC (100% Copper) Wire
The wire we use to wind the voice coil is imported from Japan which is waybetter quality than the standard China wire
60 Oz High Quality Magnet
Cast Iron Basket With Black Sanded Finish
Fiber Reinforced Ultra Stiff Black Non-Pressed Paper Cone – This cone is veryefficient which makes the speaker sound louder even without requiring a lot ofpower to push it
Thick Foam Surround Provides Incredible Sound Quality With Minimal Distortion
Blue Stitching Cone Reinforcement Ensures Long Life
Paper Dust cap is light weight and efficient helping the sub to play louder evenif your amp is not so powerful
Chrome-Plated Binding Post Terminals - These are the best terminals on themarket and they accept any gauge wire
Impedance: Single 4-Ohm Voice Coils
Vented Hole on T-yoke Enhances Heat Dissipation
Rubber Boot Magnet Covers Make the Woofer Look Nice and Protects the Magnet
Mounting Gasket with Rockville branding looks great and Makes it Easy To Mountthe Subwoofer Air-Tight
High BL Magnetic Motor Gap
We use the highest grade black glue that handles extremely high temperatureswhich allows our woofer to handle even more power than they are rated
